Claims.

This invention relates to cigar machines and more particularly to improved rolling mechanism for forming cigar bunches.

The chief object of this invention is to achieve a simplicity in construction which will greatly benet the operation of a cigar machine by the provision of a simplified rolling pin structure so designed that the number of elements required ior each unit has been materially reduced with a concurrent increase in general machine ei'liciency.

The invention also consists of an improved rolling pin mechanism wherein the rolling pin has been mounted on a movable carriage provided with self-aligning pin supporting bearings which allow changes of rolling pins for various selected cigar shapes to be effected with a minimum of expenditure in time and effort.

It is a further object of the invention to provide improved rolling pin mechanism having means for adjusting the pin at any desired angle with respect to the rolling table and mounts which allow rolling pins to be changed with a minimum of effort whenever a different taper of cigar is to be formed on the machine.

The invention is further characterized in the provision of adjustable rolling pin supporting mechanism so constructed and arranged that the means which control the movement and operation of the rolling pin are mounted below the plane of the rolling table thereby making it possible to eliminate control or operating mechanism such as stationary trailer cam means which have been previously used in some cigar machines of this type.

*ith these and other objects not specically mentioned in View, the invention consists in certain combinations and constructions which will be hereinafter fully described, and then specifically set forth in the claims hereuntorappended.

In the accompanying drawing which forms a part of this specification, and wherein the several reference characters designate the same or like elements:

Fig. 1 is a partial plan view of binder apron rolling mechanism;

Fig. 2 is a sectional elevation of Fig. 1;

Fig. 3 is an end elevation of Fig. 1; and

Fig, 4 is a sectional diagrammatic view showing the filler charge being rolled into a tapered shape in the rolling apron by the tapered rolling pin.

The construction herewith presented has a flexibility covering the entire range of shapes of cigars, from cylindrical to any amount of taper of body.

When producing cigars with cylindrical bodies a straight rolling table and a straight rolling apron are used vWith a cylindrical rolling pin, but when producing cigars with tapered bodies it has .been found desirable to use an apron and a rolling table having a curvature corresponding to the taper of the cigar, and operated by a coni-cal rolling pin, the apex of which should be approximately the same as the apex of the conical body of the cigar. The curvature of the rolling table and the apron should also be struck ifrom the apex point above mentioned.

The rolling pin housing II receives its motion from a cam disk on the drive shaft (not shown) by camflever 'I2 through an adjustable connecting rod I3.

The housing I I has two pairs of rollers, one pair I4 on vertical pins I5 and one pair IB on horizontal pins I'I. These rollers travel in cam tracks I8 and I9, respectively. The curvature of these tracks is struck from the apex point of the conical rolling pin 2).

The cam tracks I8 and I9 are preferably formed in an adjuslable bracket I4!) attached to the rolling table 2l by screws 2l. The holes 21a for these screws in the rolling table 2| are elongated in order to provide for shifting the bracket lili), and its cam tracks formed therein, to move the rolling pin 2D to or from the table.

The rolling pin 2i] at one end is mounted in self-aligning bearings 22 and 23, one bearing 22 being located in the main part of housing II and the other bearing 23 being iixed in housing 24 adjustably secured to the main housing II by screws 26 passing through slotted openings 36a. in order that bearing 23 may be quickly adjusted to any desired position. The rolling pin 2S is provided with a shaft portion 2da. A shoulder 2th ofrolling pin 20 serves to hold a retaining flange 23o against bearing 22, and a sleeve 2in1y on shaft 2Go is provided to space the bearings 22 and 23, said parts of the bearing unit being secured in position by a retaining Washer 2de and by a screw 261, which threads into the end 'of shaft 23a. The screw holes 26a in housing 24 are slotted so as to permit the adjustment of housing 24 as above described. The term self-aligning is used herein to indicate the fact that when the angle of the axis of pin 2|] relatively to the part 2i is changed by shifting the housing 24, the bearing 22 does not require any change to be made manually, inasmuch as the arcuate disposition f itsv rings permits lthe'lo'alls to function properly at al1 angular positions of the pin 20.

When a conical rolling pin is to be used, screws 26 are loosened and housing 24 with its included bearing 23, is shifted a suitable amount until the bottom surface of the conical rolling pin has been brought parallel to the top of the rolllng table 2l. As the bearing 23 is shifted down in a straight line it causes a slight horizontal displacement of bearing 22 which is automatically accomplished by allowing the outer bearing race to float in housing II. The other end, or the outboard end of rolling pin 20 is mounted in an adjustable bracket 299 provided with a cam track 29 in which runs a cam follower 30 mounted on the end of a rolling pin. In Fig. 2 is shown a completed adjustment for a conical rolling Din.

While making this adjustment the bracket 290 containing cam track 29 for the outboard follower 30 of the rolling pin 2G is removed; and at the completion of the adjustment it is replaced and secured at a height corresponding with the adjusted position of cam follower 30. Elongated slots Sia for screws 3l are formed in bracket 290 thereby permitting the bracket to be adjustably attached to the machine thus making it possible to regulate the position of cam track 29. After adjustments have been completed and a filler-charge 32 has been deposited on the apron 33, the rolling pin housing I I through its connections, as before described, starts a forward motion, the rolling pin 2li picks up the slack of the apron 33 which envelops the filler charge 32 and rolls it on the rolling table 2I. As it advances, the apron is pulled taut by a drum 34 (Fig. 4) thus squeezing the filler charge 32 in the apron 33 between the rolling pin 20 and the table 2 I As the rolling operation proceeds the filler charge 32 rolls over and is enveloped by the binder leaf 35 which has been deposited and held, by suction, in a predetermined position on the apron 33.

As the binder leaf 35 is placed on the apron and before the rolling movement starts, the paste applier of paster mechanism, not shown, deposits paste on the binder leaf for securing the filler in the binder.

At the end of the rolling operation the bunch is dropped over the edge of the rolling table 2| ready to be transferred by conventional means (notJ shown) f-or the wrapping and finishing operations.

The invention above described may be varied in construction within the scope of the claims for the particular device, selected to illustrate the invention, is but one of many possible concrete embodiments of the same.
